` 10 Claims. S12-141) f the front plane of the cabinet. The back of the My invention relates to sinks and cabinets, and particularly to a cabinet and sink of sheet metal construction in which the cabinet forms a support for the sink and the associated drainboards and provides drawers and compartmentsfor storage.

While sinks and cabinets of the sheet metal type have been constructed heretofore in the art, the present invention embodies new and novel structure and methods for producing such 4as- I'he cabinetis formed of a pair of end 'walls secured together by suitable framing ele ments upon a base over whichthe front of the cabinet overhangs. Oilfset doors enclose the front of the cabinet when supported on suitable ways by rollers which permit the movement of one door in overlapping relation with the other. Between the top of the doors and the top of the cabinet, drawers may be provided which are susfpended on trackways of simple unique construction. l

'The sink and drainboards along with the splashb'oard and the marginal edge is formed from a unit sheet of metal in a minimum number of die and bending operations. The marginal cabinet is interconnected at the top by an angle 'I'he drawers have projecting iianges at the top`s which engage the trackways and fare supported thereby. Channel shaped cross braces may be y? secured between the front and 'back top rails to provide additional strength thereto.

- Accordingly. the main objects of my invention edge of the sink at the sides rand front extends upwardly above the drainboard and the back ledge between the sink basin and v the splashboard, the latter of which -projects upwardly above the marginal edge. I'he drainboard is preferably fiat, having channels debossed therein I l which slope` toward the basin. The at surface of the drainboard supports dishes, pans, and other utensils, and the water draining therefrom is collected into the sloping channels and drained into the basin.

The sink is supported on a plurality of bolts projecting upwardly from. the front' and side walls of the'cabinet, engaging the underside of the marginal top ilange about the front and side ledges of the sink. Rubber caps aregpreferably provided on the heads of the bolts to insulate the sink and cabinet against the conduction of sound. Three cross bars are utilized for interconnecting the front ends of the sidepanels, the lower and intermediate pair carrying suitable rail elements which are engaged bythe door rollers. The-doors covering the 'openings are metal panels having are: to provide asink having a basin and drainboard about the edge of which a marginal rolled flange is'provided extending thereabove and terminating at the rear in asplashboard; to provide a drainboard and a ledge at the Iside and back of a sink disposed ina lplane surface having channels formed therein tapering toward the sink basin; to provide a ledge between the basin of asink and the splashboard at the back,.with.indented soap dish portions having a drain opening into the .sink basin; tosupport the sink upon a cabinet on a plurality of bolts which .are adjustablymoun-ted on the cabinet edges; to form a cabinet for a' sink from side 'v walls interconnected at. the vfront by rail elements, the bottom one of which is extended to form a door for the cabinet; to interconnect the central and lower rail of the cabinet with doors wardly projecting top ilanges on the drawer projject; to support the`cabinet on a base formed of sheet metal-of angularconstruction, which is welded or otherwise secured to nanges of the side panels and the floor of the cabinet inwardf l l structionand economical lof manufacture.

projecting-arms on which-the vrollers are plv oted, adjacent doors being so mounted as to operate' in different planes so as to be movable in overlapping relation to each other.

The bottcm rail is extended to form the 'oor oi the cabinet, supported on a base made ofzsection, which at. the front extends. inwardly of Otherobjects and features of novelty of my invention will be either sp'eciilcally pointed out or will become apparent when referring, for abetter understanding of my invention, vto the following description taken in conjunction with the accompanying drawings, wherein: v

The usual drain openings 3i is provided in the central bottom of thebasin 2| toward which the surface o! the basin slopes. A cabinet 32 is formed of sheet metal stampings and is employed for supporting a sink. l

The cabinet ls constructed of end panels 3 3 nanged inwardly at 34 at the rear and at the front at 35. The panels 33V are provided with a flange 3B on the bottom, which rests upon a ange 31 of a channel shaped side wall 38 of a base 39. At the iront, the base has an outwardly disposed. ange 4i oiset above the ange 31 at the side. The :door panel 42 for the cabinet rests upon the ange 4I and is welded or otherwise secured thereto. The panel projects forwardly of the base at 4,3 and is flanged downwardly at do and inwardly at 45 to provide a finished edge. The flange v35 at the front of theside panel 33 is hanged inwardly at 45, which ange is bent outwardly at the bottom at 41 to provide a tab by which the flange 46 may be welded to the door panel 42.

The portion 48 of the side wall 33 below the flange 35 projects forwardly and is shaped to conform tothe shape of the anges 44 and 45 over which they project to provide a finished A tab-49.0n the projection 48 provides means whereby the ange 44 may be welded thereto. The floor panel 42 has a flange 52 and interconnected and abutted against a back panel 55. Gusset plates 55 extend across the end portions of the back wall of the cabinet, connected across the corners of the base 39.*on the inwardly directed flanges 5B thereof.

The storage compartment 51, enclosed by the side panels 33 and the rear panels 54, is a compartment which is divided by partitions 58 which are ilanged outwardly at the bottom at 59 and vwelded or.I otherwise secured to the floor panel 12j At the front, the panels 58 are anged outwardly at 6I. and inwardly at 62 to form a iinished edge, thefange 62 being anged outwardly at the bottom at B3 .toprovide a-weldingtab. At the top the panel 58 is arged outwardly at 54 to'iorm a top iinished edgeybelowA thedrawers of the cabinet. The rear edge of the partition 58 mates with the inwardly extending ange 65 on the panel 54 and is welded thereto. The

5i at the rear edge which is flanged inwardly at?k panel 64 is connected to the opposite side panel or-otherwise. secured to the flange 68 on top of the panel 54.

As illustrated more particularly in Fig. 9, the panel or panels 54 have angle brackets 69 to which a guiding and supporting track 1|, for a drawer, is welded or otherwise secured. The

y opposite end of the track is `welded or otherwise secured to a ilange 12 of a panel 13 disposed above the door openings of the cabinet. 'Angularly disposed braces 14 interconnect the top front cross bar 15l with the ange 66 of the rear panel 54;

'I'he top edge of the'sidepanels 16 of a drawer 11 is flanged outwardly at 18 and downwardly at 19 and extended within the vchannel portion 8i of the trackl1l. vThe channel portion '8| has the 'e lower sideleg 82, over which the ange 19 projects, extended upwardly at a material angle.. Thetracks 1| provide a rigid support for the drawers on -the legs 82 while the legs 83, disposed adjacent thereto, prevents the drawers from tilting.I 'I'he drawer is provided with a spring latch 84 on its one side, as illustrated in Figs. 27 and 28.-

'I'he spring latch is formedof a strap of spring material secured to the side Wall 16 of the drawer and extends outwardly in a position engageable with the sid panel 13 at the door opening, Pressing inwardly on the end 85 of the spring latch' 84 permits the latch to clear the panel 13' and the door may then .be removed. The opposite drawer supporting track 86 illustrated in Figs. 7 and 8. 'Ihe trackis supported on the rear panel' 64 bythe angle bracket 69 to which the anges are welded. The oppo- Y site ena of the track ss is secured to the aange 4e Y y .to the topV flange 89 on the side vpanel for the purpose 'of supporting studs 9| 'having the head enclosed in a rubber block 92.y The bolts engage the vunderside of the rolled iiange edge of the sink and provide an adjustabe support'therefor.'v

An angle pillarbrace' 93; may be employed-to reinforce the corner fiangesyl'and 46 on the' side panel 33, as illustrated in Fig. 27.' As alsov illustrated in the figure, the front drawer. panel 94 is of box section construction, beingwfvormed of anv exterior' panel s95 having inwardly' flanged edges Iwhich lmate with the .inwardlyfangededges of an inner panel 06. ,The two side panels 16 and the bottom paneljfl of- .thedrawers 'are formell of a unit sheet"ofme tal,-asj ilrustrated preferably- 'a separate panel vsecured to the bottorn and side panels :preferably vby welding. -A U- shaped stamping 99 t may 'be disposed inthe central part of the bottom panel: 91 of the'drawer to form compartments. as illustrated in Fig. 4.

In Figs. 5, 6, 7, andfslo, I have illustrated the -Qmedial cross bar |0| as being of Z formation, the

'. upwardly disposed leg |02 beingfianged inwardly at |03 to form a -ledge for the drawer, and,4 downwardly at |04 to provide further' strength to 'the ledge. The web portion |05has a trackway |06 secured thereto, engageable by the rollers |01 on "Isin,
